Title: Overrun brake system for trailer
Inventor: DOWE GUENTHER
IPC: B60T7/20
Filed: 1982-03-20
Abstract: The invention relates to an overrun brake system for trailers, in which an overrun linkage, a parking brake and a drawbar act without any separate reverse lock by way of expansion elements on drum brakes, the brake shoes of which in reverse travel can deviate from their frictional contact position and in which a tube with a spring actuator is connected to the overrun linkage, which actuator, when the parking brake is applied, is preloaded by a rod and compensates for the deviation travel of the brake shoes in reverse travel. In order to be able to use an overrun brake system of this type in conjunction with a drawbar and an automatic reverse system, it is proposed to arrange in the tube for the spring actuator a stop for the parking brake which can be released and shifted with the rod of the handbrake lever. The invention also relates to the design principle for this stop.

Patent DE-3318484-A1 (DE)
Title: Channel selector circuit for digital bit-interleaved broadband channels
Inventor: HEYDT GUENTER ING GRAD
IPC: H04N21/434
Filed: 1983-05-19
Abstract: At the subscriber level, a large range of narrow- and broadband services should be available. These can be separated, for example, by means of wavelength-division multiplexing. For moving-picture channels (colour TV, 625 lines), about 70 Mbit/s each are needed, and for moving pictures with higher resolution (HDTV) approximately four times the bit rate, that is to say 280 Mbit/s. A multi-channel system with time division for this purpose requires relatively little circuit expenditure when the individual bit streams are available in bit-serial form and can be easily separated from one another in this form. The channel selector according to the invention is used for this purpose. It consists essentially of a sampling stage, for example a D-type flip flop, by means of which the relevant moving- picture channel is selected and supplied to the terminal, of a divider for speed conversion and of a phase shifter by means of which the relevant time slot is determined. This is done in continuously successive overlapping steps until the time slot allocated to the selected channel is reached. The divider ratio can be set for TV (present standard) and HDTV. <IMAGE>

Title: Connecting element, in particular for the releasable connection of two flat parts abutting one another at right angles in furniture
Inventor: HEIDER EGON
IPC: F16B12/20
Filed: 1984-07-17
Abstract: In furniture construction, so-called eccentric connections are known for releasable connection, in which the forces, which are initially absorbed only by the bearing bush, are transmitted to the eccentric only after the eccentric has been rotated. By the design of the connecting element according to the invention, the bearing bush no longer has a supporting function since the forces occurring on retention of the dowel head are already taken over by the eccentric. For this purpose, the inner side of the eccentric has a circumferential, outer edge for retaining the head of the dowel, the inner side of the eccentric being constructed as a circumferential, closed ring in the embodiment of the invention. The connecting element according to the invention allows a lighter design of the bearing bush which can also be constructed as a hinged bush, as a result of which the insertion of the eccentric in the bearing bush is facilitated.

Title: Continuous system for treating coated mouldings with high-energy radiation
Inventor: MARTIN WOLFRAM DIPL ING
IPC: B05D3/06
Filed: 1984-07-25
Abstract: In a continuous system for treating coated mouldings with high-energy radiation, having a conveying zone, an irradiation region provided in the course of the conveying zone and an irradiation device and having a shield which encloses the conveying zone in the irradiation region and on both sides thereof in the form of an inlet channel and an outlet channel, in order to achieve a higher throughput of mouldings per unit time with a simpler design, it is proposed that the longitudinal axes of the inlet channel and of the outlet channel deviate one or more times from a straight line so as to suppress a dispersion of radiation occurring in the irradiation region in the direction of these longitudinal axes.
Patent DE-3429023-A1 (DE)
Inventor: BUDDENBERG JOERG WOLFGANG
IPC: B65G65/30
Filed: 1984-08-07
Abstract: A silo (1) intended for bulk material, having a circular ground layout, possessing a central, torsion-resistant supporting column (4), for a filling system (9) which can be loaded from above and can rotate around the central axis, and two transverse conveyors which are arranged on the supporting column (4) so that they can be raised or lowered, and rotated around the supporting column (4). The transverse conveyor consists of two clearing arms (19) which are secured to the rotary part (17) of a lifting and rotating frame (13) and are designed with a curved shape and extend approximately to the silo wall. When the silo is being filled, the clearing arms (19) are rotated around the supporting column (40 in such a way that they push and distribute the bulk material outwards with their convex external edges. On the other hand, to empty, the clearing arms (19) are rotated in the opposite direction so that they deflect inwards the bulk material with their concave inner edges and push it through the openings in the helical strip (5) of the supporting column (4) in the evacuation shaft (7). The arrangement and design of the clearing arms (19) in the form of hook-shaped arms is of valuable importance and especially suited for medium-size silos (1).
Patent DE-3438226-A1 (DE)
Title: Apparatus for erasing programmable electronic memories
Inventor: WELTER HEINZ
IPC: G11C16/18
Filed: 1984-10-18
Abstract: The invention relates to an apparatus for erasing programmable electronic memories, having an apparatus housing, having a lamp which is arranged therein and produces UV light, having an intermediate panel which has a recess which is used as a light outlet, having a cover which can be placed on the apparatus housing or on the intermediate panel, and having a switch which is used for operating the lamp.

Title: UV metal halide lamp (burner) for cosmetic purposes
Inventor: PIRKL JOSEF
IPC: H01J61/40
Filed: 1984-10-19
Abstract: The invention relates to a UV metal halide lamp (burner) for cosmetic purposes, having a bulb (1) made from high-melting, pure quartz, the ends (2, 3) of which are pinched and are fused in a vacuum-tight fashion into the electrical bushings (4). In order to prevent any disadvantageous consequences of cosmetic irradiation, it is required that in these lamps (burners) the ratio of radiation up to 260 nm to radiation above 260 nm may not be greater than 0.003; moreover, the UVB component may not be higher than 5%. These requirements must be satisfied in every direction of radiation of the UV lamp (burner). In order to fulfil this precondition and, moreover, to render it possible for the lamp (burner) to be used in existing tanning units and systems in a simple and rapid way without the need for complicated conversion work, it is proposed according to the invention that the bulb (1) is surrounded by a cylindrical radiation filter (5), the end faces of which are sealed by respective caps (6, 7) which have passage openings for the pinched ends (2, 3) of the bulb (1). <IMAGE>
